takes a few minutes. Join Now I have an ASA 5505 on a back-up link that I sometimes use for testing. I need to set a static PAT translation for port 443 from the outside
Change Asdm Port
to an internal server. I changed the port that the ASDM uses with: ASA(config)#http server enable 4443 i even ran a "clear xlate" and a reload and I still get a "unable to reserve port 443 for static PAT" error. I cannot seem to find anything else that is using 443..... This has got me stumped...quick 5 minute task taking hours to fix :-) Reply Subscribe View Best Answer RELATED TOPICS: Exxchange https://supportforums.cisco.com/discussion/11601726/error-nat-unable-reserve-ports 2007 Behind ASA 5505 not Receiving Mail ASA 5505 set up question ASA 5505 // Advice needed   9 Replies Poblano OP JR4993 Jul 18, 2013 at 10:03 UTC It's been so long since I did this on my end but do you still have the "http server enable 443" in the config, even though you enabled 4443, 443 might still be there: no http server enable 443 0 https://community.spiceworks.com/topic/360346-asa-5505-port-reservation-not-allowed Serrano OP Tobakslovakian Jul 19, 2013 at 2:39 UTC Run packet tracer under ASDM and view which rule in the config is matching that traffic type (source: outside, destination: inside port 443). 0 Jalapeno OP Steve.Melcher Jul 19, 2013 at 3:48 UTC I already disabled the HTTP server...still no avail. 0 Jalapeno OP Steve.Melcher Jul 19, 2013 at 3:51 UTC The packet tracer says it is associated with the default security policy on the firewall and will not show the access rule that is passing the traffic. route look-up passes The packet is dropped because Slowpath security checks fail. Still no closer to figuring this out. 0 Jalapeno OP Steve.Melcher Jul 19, 2013 at 4:37 UTC I think the issue is AnyConnect VPN settings. Doesn't that use 443? I have never changed it...not sure how... 0 Serrano OP Best Answer Tobakslovakian Jul 19, 2013 at 4:49 UTC Could also go to advanced ACL Manager and do a service search for https and see what rule it hits. Anyconnect would be under Remote Access VPN -> Clientless SSL VPN Connection; see if that is enabled. 1 Jalapeno OP Steve.Melcher Jul 19, 2013 at 4:57
Post #1 of 2 (2769 views) Permalink Cisco ASA PAT issues with dynamic translations, any ideas? OK, I am sure this is just something I haven't run into before, but I http://www.gossamer-threads.com/lists/cisco/nsp/114572 just setup an ASA5520, and overall it's doing well, except this one gotcha. We are using it in routed/NAT mode, but some internal servers need to be on their own external IP's as well, we have multiple DNS, Mail, and so on servers in the network. I have the external IP's on the firewall, mapped to the specific internal servers, and all is well. Also my TCP mappings all seem to be fine, but unable to when I try and put in a translation for UDP on port 53 it has a cow. ERROR: unable to reserve port 53 for static PAT ERROR: unable to download policy So needless to say the outside DNS queries to that server are NOT working.. L Here is some of my config, hopefully I don't need to post it all as it's quite extensive (with multiple VPN's and so on), so I will try unable to reserve and post what I think are the relevant parts. name 10.98.4.33 MAIL1-Inside name 207.xx.xx.33 MAIL1-Outside object-group protocol TCPUDP protocol-object udp protocol-object tcp access-list Internet_access_in remark DNS Server on MAIL1 access-list Internet_access_in extended permit object-group TCPUDP any host MAIL1-Outside eq domain nat-control global (Internet) 101 interface global (Internet) 102 MAIL1-Outside netmask 255.0.0.0 nat (LAN) 0 access-list LAN_nat0_outbound nat (LAN) 102 MAIL1-Inside 255.255.255.255 nat (LAN) 101 0.0.0.0 0.0.0.0 static (LAN,Internet) tcp MAIL1-Outside domain MAIL1-Inside domain netmask 255.255.255.255 static (LAN,Internet) tcp MAIL1-Outside smtp MAIL1-Inside smtp netmask 255.255.255.255 NOTE: The TCP static translations above works just fine, but if I try and put in a UDP translation as well like this: static (LAN,Internet) udp MAIL1-Outside domain MAIL1-Inside domain netmask 255.255.255.255 The ASA throws a bitch and kicks out "ERROR: unable to reserve port 53 for static PAT" error. Of course without UDP on port 53 working, DNS lookups from that machine to the outside world are dead. What am I missing here?? I know if I didn't have it on it's own specific external IP, then I could put in the UDP rule (as I have some in for servers that don't need there own), but if I pull that, then I don't have the server on it's own IP, and then mail/SMTP service becomes an issue as some sites reject unreachable mail servers.
